The present invention relates to a kit of parts comprising a dental mill blank comprising a porous zirconia material and a colouring solution for colouring the porous zirconia material. The porous zirconia material comprises Zr oxide calculated as ZrO2: from 80 to 97 wt.-%, Al oxide calculated as Al2O3: from 0 to 0.15 wt.-%, Y oxide calculated as Y2O3: from 1 to 10 wt.-%, Bi oxide calculated as Bi2O3: from 0.01 to 0.2 wt.-%, the porous zirconia material not comprising Fe calculated as Fe2O3 in an amount of more than 0.01 wt.-%, wt.-% with respect to the weight of the porous zirconia material. The colouring solution comprises solvent(s), colouring agent(s) comprising metal ions selected from Tb, Er, Pr, Mn or combinations thereof, the solution not comprising Fe ions in an amount of more than 0.01 wt.-%, the solution not comprising Bi ions in an amount of more than 0.01 wt.-%, wt.-% with respect to the weight of the colouring solution. The invention also relates to a process of producing a dental restoration, the process comprising the steps: providing a dental mill blank comprising a porous zirconia material as described in any of the preceding claims, machining an article out of the porous zirconia material, the article having the shape of a dental restoration with an outer and inner surface, providing a colouring solution as described in any of the preceding claims, applying the colouring solution to at least portions of the surface of the article having the shape of a dental restoration.

A method of taking a scan of a patient's oral cavity may include providing an anatomical healing cap that can be received within a subgingival void of a given tooth position. The method may also include taking a first scan (e.g., an extraoral scan) of the anatomical healing cap before seating the anatomical healing cap into the subgingival void of the given tooth position, where the anatomical healing cap is coupled to an implant disposed adjacent the anatomical healing cap. Further, the method can involve taking a second scan (e.g., an intraoral scan) of the anatomical healing cap and surrounding surfaces, and then integrating the two scans into an overall oral cavity scan. Reference points from the first scan may be used to align the second scan with the first scan, integrating the two together.

A dental implant assembly comprising a healing component (10) removably attachable to a coronal end of a dental implant (40) and an impression component (20) having an outer surface, an upper portion (21) and a lower portion (22) and being removably attachable to the healing component (10). The healing component (10) has an internal bore (13) for receiving at least part of the lower portion (22) of said impression component (20) therein and the internal bore having a shoulder on an inner surface thereof acting as an axial locator providing an endstop for axial movement of said impression component (20) within said bore (13). The assembly further comprises a rotational locator limiting rotational movement between said impression component (20) and said healing component (10), the rotational locator comprising a formation on said outer surface of the impression component (20) and/or a formation on said inner surface of said bore (13) of the healing component (10). Using this assembly, a digital impression recording positional information about the dental implant can be taken without having to remove the healing component (10) from the implant (40).

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.

Disclosed herein is a preliminary guide including an impression resin and a guide tray. The guide tray includes an impression resin accommodation part, a jig fastening part, a protective cover part, and a grip part.

An implant-supported denture placement and alignment system may include a denture apparatus. The denture apparatus may have a denture base and a denture base positioning system. The denture base may comprise an implant guide system and be connectable to implants. In this manner, the denture apparatus may be positioned so that it is mountable to the implants placed according to the implant guide following their placement in a patient's mouth.

A dental implant for insertion in a jaw bone has a receiving opening arranged on a coronal end of the dental implant for an abutment, the receiving opening when viewed from the coronal end having a taper section and an indexing section, the indexing section having at least one outwardly extending groove arranged along a circular circumference, the taper section having a conical angle of less than 3.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. The casting jig includes an opening through the bottom surface through which an elongate handle may be inserted, allowing a temporary abutment to be coupled into the distal end of the elongate handle, so that the abutment is disposed in the well, held in place by the handle, as it is used as a core about which the anatomical healing cuff body is formed. A crown forming jig for forming an inexpensive, chair-side prepared bis-acrylic temporary crown that may be easily and quickly installed over the anatomical healing cuff body is also disclosed.

Casting jigs, methods, and kits that may be used in manufacture of anatomical healing caps. A casting jig may include a body having one or more wells within the body, each well being open at a proximal end thereof and having a negative shape corresponding to an anatomical healing cuff body of a given tooth position. Each respective anatomical healing cuff body negative shape includes an asymmetrical cross-section and an irregular surface so that an anatomical healing cuff body having said shape is configured to provide substantially custom filling of at least an emergence portion of a void where a natural tooth once emerged or should have emerged from the void (e.g., in the case of a congenitally missing tooth). The casting jig may further include a socket at a distal end of each well that is configured to receive therein a dental implant or dental implant analog.

The present application describes an implant-supported denture device and a method for designing and manufacturing an implant-supported denture device for a patient. A method is described for designing a virtual denture and manufacturing an implant-supported functional fitting replica denture from the virtual denture. An apparatus comprising a functional fitting replica denture is prepared having denture teeth having a fit substantially similar to the final denture. The methods and apparatus described herein reduce the number of visits required to manufacture the final denture.
